动词的语态
英语的语态分为主动语态和被动语态。主动语态表示主语是动作的执行者, 被动语态表示主语是动作的承受者。
只有及物动词或短语才能转换成被动语态。
一:动词的被动语态概念
主动语态:主语是动作的执行者Many people speak English.
被动语态:主语是动作的承受者
English is spoken by many people.
二、需要使用被动语态的情况:
当我们不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者,或者只需强调动作的承受者时,要用被动语态。
e.g. Such books are written for middle school
students.
English is spoken in many countries.
三、被动语态的构成:
被动语态是由“助动词be +及物动词的过去分词”构成,be随主语的人称、单复数和时态的变化而变化。被动语态可以用于各种时态。
被动语态的构成(以do为例)
现在时 过去时 将来时 过去将来时
一 般 is/am/are done was/were done will/shall be done would/should
be done
进 行 is/am/are being done was/were being done
完 成 have/has been done had been done will/shall have been done would/should have been done
例 The railway was built in 1998.这条铁路建于1998 年。(一般过去时的被动语态)
例 A new railway is being built in this city.这个城市正在修建一条新的铁路。(现在进行时的被动语态)
例 The railway was being built this time last year.去年这个时候这条铁路正在修建。(过去进行时的被动语态)
例 The railway has already been built.那条铁路已经建成了。(现在完成时的被动语态)
例 The railway had been built by the end of last year.这条铁路在去年年底前已经建成了。(过去完成时的被动语态)
例 A new railway will be built in this city next year.这个城市明年将建一条新的铁路。(一般将来时的被动语态)
例 He told us that a new railway would be built the next year.他告诉我们下一年将修建一条新铁路。(宾语从句的谓语动词用的是过去将来时的被动语态)
(1) 带情态动词的被动语态,由“情态动词 +be+过去分词”构成。
e.g. The problem may be solved in a number of different ways.
In our school, library books must be returned in two weeks.
四.被动语态的常见用法
(2) 含有be going to,be to,used to,be about to等结构的复合谓语变为被动语态,其构成为be going to(be to,used to,be about to)+be +动词的过去分词。
e.g. This book is going to be translated into 6 languages.
(3)“sb+be+过去分词+不定式”= “it+be+过去分词+that从句”
e.g. He is reported to have broken a world record.
It is reported that he have broken a world record.
She is said to know three languages.
It is said that she know three languages.
常见的结构还有:
It is known that... 众所周知
It is suggested that... 有人建议
It is believed that... 人们相信
(4) “get/be+动词的过去分词”不强调被动用来强调状态或情况, 常考的形式如下:
get/be married 结婚;get/be engaged 订婚
get/be hurt/wounded 受伤;get lost 迷路
get/be drunk 喝醉了
get/be caught/stuck/trapped in被困,陷入
get/be dressed in 穿着
be tired疲惫 be shocked 震惊
五、不能使用被动语态的情况:
(一)不及物动词(短语)不用于被动语态,如happen, occur, take place, break out, spread等。
例 A fire broke out in the forest.森林里爆发了一场火灾。
例 The news spreads quickly.这一消息传播得很快。
(二)表示归属的动词(短语)不用于被动语态,如have, own, belong to等。
例 The blue car belongs to me.那辆蓝色的汽车属于我。
1.动词write, read, sell, wash,open等与well, badly, easily等副词连用表示主语特征时用主动形式表示被动意义。
例 The cloth washes easily.这布很好洗。
例 The new product sells well.这种新产品很畅销。
2.need,require,want,deserve,bear(经得住)和be worth后接动名词,动名词用主动形式表示被动意义,相当于动词不定式的被动形式。
例 My watch doesn’t work; it needs repairing.我的手表坏了,需要修理。
例 This film is really worth seeing.这部电影的确值得看。
(三) 主动形式表示被动意义
3.系动词feel, look, seem, taste, sound, remain等后接形容词作表语时一般用主动形式表示被动意义。
例 Your advice sounds practical.你的建议听起来是可行的。
例 The food tastes delicious.这种食物尝起来味道很好。
This kind of wool shirt     (feel) soft and   (sell) well.
feels
sells
4.在“主语+be + 形容词+ (for sb.)+不定式”结构中,不定式表示的动作与句子主语之间是逻辑上的动宾关系时,用主动形式表示被动意义。用于此结构的常见形容词有:cheap, easy, comfortable, difficult, hard, light, heavy, expensive, pleasant, interesting, fit 等。
e.g. The question is difficult to answer.
Volleyball is very interesting to watch.
5.be to blame应受责备,be to rent待租,也属于主动形式表被动意义。
You shoud be to blame for the mistake.
